Water under driver side back seat

[patholland]

I was cleaning the inside of my car a couple weeks ago and noticed the carpet under the driver side back seat was wet, and also under the mat on the floorboard. I vacuumed the water, but it reappeared a few days later. The soft top does not leak to my knowledge. What could cause this?

Do a search here for "drains". You will find locations and cleaning instructions.

Make sure you immediatly remove the driver's seat and get the Alarm Module that is mounted under it out of the car and open up it to dry out.

Even if it it doesn't seem wet, when you brake the water flows forward and will ruin it.

$2k+ repair if it needs to be replaced.

Pat:

Here is the text of a post that member "Kim" posted back in July of this year:

"When you read through the link that Loren supplied, read carefully. There are two related, but distinctly separate causes of the rear cab drain system leaks.

1. The simplest: a clogged drain valve located behind the forward wall of the rear wheel well cover. Clean it out, and you're done.

2. A problem behind the rear seat side wall panel, where the upper cab drain tray drains into the lower cab drain tray (from which the tube runs to the wheel well). In my case, there was a leaking connection on the hose between the two.

I have also seen a crack in the upper tray nipple that leads into the tube to the lower tray.

I have also seen the tube to the lower tray displaced, so that it drains free into the car behind the side panel.

Any of these problems can cause the floor carpet and carpet under the rear seat cushion to be soaked following a car wash or rain.

If you have the tray related problems, you can search for my thread in the Feb, 05 vicinity. In it, I detail how to remove the rear seat back (unusual tool required) and how to get into the tray area itself."

By the way, I strongly urge you to heed Blakester's advice regarding the alarm computer under the driver's seat.

Good Luck!
